Embodiment Construction
[0032] 1. The subject wears a heart rate monitor or heart rate belt that can continuously monitor the heart rate;
[0033] 2. Record the heart rate of the subject during exercise and calculate the average value;
[0034] 3. Calculate the oxygen uptake during exercise through the prediction method;
[0035] 4. By checking the average heart rate in step 2, you can get the intensity range of the overall exercise; you can also observe the real-time heart rate during exercise to control the exercise intensity within the predetermined intensity range.

A method for calculating adolescents' oxygen intake and exercise intensity in daily activities by the load heart rate belongs to the field of health assessment. The oxygen intake is considered to be associated with a variety of disease risks, so the oxygen intake is critical. Direct measurement of the oxygen intake requires very precise instruments which usually only exist in experimental researchand can not be applied in the field of public physical training. The method uses the oxygen intake collected by a gas metabolic analyzer as the 'gold standard' and establishes a multiple regression equation with other variables such as sex and age. The result of backdating verification shows that the method has high reliability and can easily and effectively predict the oxygen intake of adolescents in daily physical activities. In addition, through the accurate measurement value of gas metabolism as a benchmark, an ROC curve analysis method is adopted, the load heart rate intervals corresponding to different intensity ranges are obtained, and the intensity of exercise is judged through the load heart rate.
Description
technical field [0001] The invention relates to a method for estimating the oxygen intake and exercise intensity of adolescents' daily activities through the load heart rate, which belongs to the field of health assessment. Whether in the assessment of energy expenditure and exercise intensity, the assessment of oxygen uptake is very critical. Oxygen uptake can be converted by oxygen heat value and energy consumption, and can also be used to compare the intensity relationship of different sports horizontally through the ratio of oxygen uptake (1 MET, MET) in a quiet state, so it is of great significance . However, the direct test of oxygen uptake requires very sophisticated instruments, such as gas metabolism chamber (chamber), gas metabolism analyzer, etc., which are expensive and usually only exist in experimental research, but cannot be applied in the field of mass fitness. In this method, the oxygen uptake collected by the gas metabolism analyzer is used as the "gold sta...
